Abstract (en)
[origin: EP0056597A2] 1. Process for the production of a shaped body of a porous heat insulating material, in which a mixture of a basic mass for ceramic material and a very finely distributed material which can be burnt away serves as starting material, and in which the mixture is brought into the required shape and sintered in an oxygen-free atmosphere at a sintering temperature, characterised in that the components of the mixture, at least the material which can be burnt away, consist of microfibres, and that after the sintering, the material which can be burnt away, is burnt away at a temperature which lies considerably below the sintering temperature.
